Indeed. As I worked on it the last few days I came up with the following:
virtual:
domains = lsearch;/etc/mail/v-domains,
driver = aliasfile;
file = /etc/mail/v-aliases/$domain,
search_type = lsearch
virtual_default:
domains = lsearch;/etc/mail/v-domains,
driver = smartuser,
no_more;
new_address = ${lookup{$domain}lsearch{/etc/mail/v-aliases/$domain}
{$value}fa
il}
And it occurs to me that the smartuser could handle it from a single file
by looking up {$local_part@$domain}, and looking up $domain if that fails.
Thanks for such a configurable mailer:)
